Definitions

  • the invention relates to a method for manufacturing load-carrying elements, in which tubular paperboard cores are disposed in a row and are assembled by means of a covering paperboard to form a beam aligned with the row of cores.
  • the invention also relates to the manufacture of a loading base such as a pallet comprising the supporting elements thus obtained.
  • Paperboard cores manufactured by gluing helically wound board layers on top of each other to form a tube with a multi-layered mantle have been conventionally used as cores in paper rolls, on which the load is exerted laterally.
  • Pallets utilising the high axial compression strength of the cores form a second object of application of paperboard cores.
  • the cores and the covering paperboard are assembled into beams, which are aligned and joined by means of a covering plate to form a pallet, in which the core axes included in the beams are perpendicular to the plane of the pallet.
  • the pallet may also comprise beams crosswise in two layers, and then no covering plate will be necessary in order to assemble the pallet.
  • Such prior art disposable pallets made of recyclable material have been disclosed by FI patent specifications 93933 and 107600 B , among other publications.
  • the beams for the pallet are manufactured by aligning the cores on a sheet of corrugated board, which is wrapped around the cores and bound to these by means of hotmelt glue.
  • the sheet and the core row have equal lengths so that the beam thus formed will have open ends.
  • FI patent specification 107600 B comprises a sheet of corrugated board shaped and dimensioned so as to surround the row of cores and also close the ends of the beam thus obtained.
  • the purpose of the invention is thus to improve the process for manufacturing beams formed of paperboard cores and covering paperboard, comprising the cutting of a previously assembled beam into sections of specific lengths.
  • the invention has the specific purpose of providing a solution by means of which a beam can be cut with less effort than before while producing a neat cutting mark.
  • the method of the invention is characterised by the fact that, before the beam is assembled, the covering board is equipped with one or more weakening lines transverse to the direction of the row of cores and in that each element formed of paperboard and cores is separated by cutting the beam along the weakening line.
  • the covering paperboard may have been weakened in advance to an extent such that no cutting tool is needed for detaching the element to be separated, i.e. the beam of a specific length forming the end product of the method, the beam being removed by a simple impact.
  • the invention does not require the cutting location to be between the cores with the same absolute precision as does cutting of the beam by means of a linear cutter movement or by sawing, and hence the cores may be located closer to each other at the cutting location and even in contact with each other without preventing cutting of the beam.
  • the weakening lines required by the invention are preferably perforations of the covering paperboard.
  • the weakening line may consist of dot-like or preferably linear perforations penetrating through the paperboard and covering the weakening line so that the portions on the two sides of the line are weakly joined only by narrow bridges between the perforations.
  • the bridges are required to have only a strength such that the paperboard can be wrapped around the cores without breaking prematurely. Previously made long linear perforations and a minimum number of bridges also achieve the most even cutting mark. Light slitting of the board surface at the bridge locations also contributes to this.
  • a weakening line can be produced in a paperboard sheet or web e.g. by means of a reciprocating tool of saw blade type, which produces linear perforations in the paperboard that separate the bridges from each other. Assuming that a light impact is enough for final cutting of the beam, cutting the beam by means of said tool in accordance with the invention is a substantially easier and more secure operation than dividing an intact beam as in the prior art operation.
  • Perforations or any similar weakening lines can be produced in the paperboard sheet or web while it is in a single plane, i.e. before starting to bend the web around the cores. It is also preferable to produce the weakening lines in the sheet or web before placing the cores on this. This allows the cores to be disposed in mutual contact also at the location of the weakening line.
  • the invention is particularly suitable for continuous manufacture of elements, i.e. beams of a specific length, which is performed by forming transverse weakening lines in a continuous paperboard web at intervals equalling the lengths of the elements, aligning cores on the web, wrapping the web around the row of cores to form a beam and dividing the beam along the weakening lines to form separate elements.
  • the invention can optionally be implemented by producing a beam of a specific length comprising one or more transverse weakening lines, the beam being divided into parts by supporting the beam between the weakening lines and directing a blow or an impact simultaneously to both ends of the beam for detaching the part to be separated.
  • the method of the invention for producing a loading base comprises the manufacture as described above of elements consisting of paperboard cores and covering paperboard, i.e. beams of specific lengths, which are disposed next to each other and bound to each other to form a base, with the base receiving the load exerted on it in the axial direction of the cores.
  • the beams can be connected to form a pallet by means of a covering plate, on which the load carried by the pallet is placed. Beams are preferably aligned on the pallet in succession and separated from each other, allowing a lifting fork to grip the rectangular pallet from all four sides of the pallet by penetrating between the beams.
  • the production line of figure 1 produces in a continuously operating process a beam 3 consisting of tubular paperboard cores 1 and surrounding covering paperboard 2, the beam being divided at the end of the process into parts of specific lengths, i.e. beam-like elements 4 of specific lengths, which, owing to their strength, are suitable for carrying load in loading bases, such as pallets, for instance.
  • Disposable pallets made entirely of paperboard have the advantage of their material being recyclable.
  • the beam 3 is formed of a continuous paperboard web 2 provided with longitudinal crease lines 5 and board core pieces 1 aligned on this.
  • the crease lines 5 divide the web 2 into a central strip 6, inner border strips 7 on both sides of this and outer border strips 8 at the edges of the web.
  • weakening lines 9 are produced at given intervals, extending from one edge of the other in the web.
  • the weakening lines 9 may consist of perforations and narrow bridges between these, which retain the web assembled at the lines.
  • the web 2 is spread in one single plane, the perforations being made by means of a reciprocating tool 10 of saw-blade type perpendicularly to the plane of the web.
  • the distance between the weakening lines 9 has been dimensioned so as to equal the summed diameters of two adjacent cores 1 in one row of cores.
  • the cores 1 are disposed in the central strip 6 of the web 2, with the weakening lines 9 intersecting the row of cores at the location 11 between every second core.
  • the weakening line 9 passes through the point at which adjacent cores 1 touch each other, even though the invention does not necessarily require such exact positioning of the cores 1 relative to the weakening line 9.
  • the contact between the cores 1 is not indispensable, but instead, it is possible to leave gaps between the individual cores or the pairs of cores between the weakening lines 9.
  • the cores are disposed on the web 2 by means of the vertically reciprocating tool 13 gripping the cores with its fork 12 as illustrated in figure 1 .
  • the cores 1 can be brought onto the web 2 in many different ways, as e.g. by pushing the cores from the side of the web or by continuously leading the cores along groove-like guides from the side or the top of the web. Such embodiments are known per se or obvious to those skilled in the art.
  • the web 2 is bent around the row of cores by means of guides (not illustrated).
  • the aligned border strips 8 form a longitudinal seam line 14 on the upper side of the beam.
  • glue is applied to the web 2 and/or the cores 1 before the web is bent.
  • the continuous beam 3 provided with transverse weakening lines 9 obtained in the last process step is divided into parts by cutting the beam along each weakening line. This results in beam-like elements 4 of specific lengths, each of which has two adjacent paperboard cores 1 surrounded by the covering paperboard 2.
  • the cutting tool consists of a hydraulically reciprocating hammer 15, which separates an element 4 by a light impact on this.
  • Figure 2 shows belt conveyors 16 moving a finished beam 3 and having the additional function of supporting the beam so that the element 4 to be separated from its end each time is separated without efforts.
  • the production of the beam 3 can differ from the procedure described above by forming the weakening lines 9 before the web 2 is provided with longitudinally scored crease lines 5.
  • the paperboard web 5 is preferably formed of a plurality of material webs on top of each other, and then the weakening lines 9 can be formed separately in each of these before the webs are joined together, so that their weakening lines coincide.
  • the material webs are bound together by means of glue, and the crease lines 5 are preferably scored to the layered structure of the web 2 before the glue dries, i.e. while the web is moistened or softened by fresh glue.
  • a covering paperboard 2 glued in multiple layers imparts the beam 3 rigidity, which facilitates the division of the beam into elements 4 and produces stronger elements for various loading applications.
  • the object of cutting is a beam 3 produced with specific dimensions and provided with weakening lines 9 enabling division.
  • the weakening lines 9 divide the beam 3 into three parts, each of which comprises two adjacent core pieces 1 surrounded by the covering paperboard 2.
  • the beam 3 has been disposed on a base 17, and cutting is performed by means of drive belts 19 rotating around the outermost parts of the beam and driven by hydraulic cylinders 18.
  • the beam 3 is divided as shown in figure 4 along weakening lines 9 into three elements 4 corresponding to figures 1 and 2 .
  • FIG. 5 illustrates a variation of the invention, in which the perforation tool cuts weakening lines 9 in the paperboard web 2, the lines matching the core pieces 1 defined by the lines and being spaced by areas 20, which are split off as the obtained continuous beam is divided into individual elements 4 as shown in figure 6 .
  • each element 4 comprises three adjacent cores 1, and the ends of the elements have been rounded so as to match the circular profile of the cores by the shape of the weakening lines 9.
  • Figure 7 shows a paperboard pallet 21, which has been formed by disposing a total of nine beam-like elements 4 obtained as in figure 1 next to each other in three longitudinal and transverse rows and by binding them together with a covering plate 22, the axes of the cores 1 included in the elements being perpendicular to the plane of the plate.
  • the covering plate 22 receives the load placed on the pallet, and the gaps 23 between the aligned elements 4 allow the loaded pallet to be shifted by means of the lifting fork of a forklift truck.
  • the application of the pallet 21 shown in figures 8-10 differs from the one of figure 7 in that, below the longitudinal rows of beam-like elements 4, base strips 24 have been disposed extending from one end to another of the rows, the base strips consisting of elongated paperboard strips having roughly the same width as that of the elements 4.
  • the longitudinal edges 25 of the strips 24 have been bent upwardly so that the strip forms a shallow groove, into which each element 4 is fitted.
  • the groove has been filled with filling paperboard 26 between the elements 4, cf. figure 10 .
  • the strips 24 and the pieces of paperboard filling 26 may consist of glued multi-layered paperboard as described above, corresponding to the one used for coating 2 the beam-like elements 4.
  • the longitudinal base strips 24 have the double purpose of strengthening the pallet and above all of allowing it to be shifted on a roller conveyor in the longitudinal direction of the strips.
  • the pallet can be lifted and shifted by means of a forklift truck owing to the gaps 23 between the rows of elements and the openings 27 between the elements 4 provided between the covering plate 22 of the pallet and the base strips 24.
  • the covering paperboard of the beams may consist of two separate webs or sheets, one of which surrounds the cores 1 on their bottom side and the other one surrounds them on their top side, so that the webs or sheets form together the longitudinal sides of the elements.
  • the cores are not necessarily surrounded by covering paperboard on all the longitudinal sides, but the beam and accordingly the elements separated from this can be left partly open, provided that the gluing is adequate for assembling the elements.
